IMPROVEMENT IN LAMP-CHIMNEYS.

Specification forming part of Letters Patent N 0. 207,280, dated August:30, 1878 application filed March 8, 1878.

To all whom it may concern:

Be it known that I, SAMUEL B. INGLIS, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Lamp-Chimneys and I do hereby declare the following to bea full, clear, and exact description of the same, reference beinghad tothe accompanying drawings, formin g part of this specification, inwhich- Figure 1 represents a vertical section, and Fig. 2 is a sideview.

This invention relates to lamp-chimneys; and consists in theconstruction and arrangement of parts, substantially as hereinafterfully described and claimed.

In the drawings, 0 (J are two equal portions of a lamp-chimney, whichmay be of any of the styles in use. 0 0 represent two clamps, providedwith screws 8 s and clamp-springs t i, and hinged to the frame of thelamp, by which the half-chimneys O G are secured to the latter.According to the disposition of the lamp, one orboth of the two halves G0 might be provided with a recess, 1", to receive the clamp 0. Twomovable springs, S S, fixed also to the frame of the lamp, keep theedges of the parts 0 0 close together. By turning these springs sidewardthe chimney can be opened and cleaned without being taken off from thelamp.

The advantages of this kind of lamp-chimneys are, that they are notexposed to break through sudden expansion or contraction, as is the casefor chimneys made in one piece, and that their cleaning outside andinside can be done far better and more easily.

What I claim as new is 1. In a lamp-chimney, the clamps c c, with theirscrews 8 s and springs z t", and hinged to the frame of the lamp, andthe springs S S, maintaining the edges of the half-chimneys together, incombination with the parts 0 C, as described and set forth.

2. The half-chimney 0, provided with a recess, r, in combination withthe clamp c, as described, and for the purpose set forth.

SAMUEL B. INGLIS.
